CIGARBUNCHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 406,329, dated July 2,1.889.v Application filed July 13, 1887. Serial No. 244,211. (No model.)

To @ZZ whom it may concern-.-

Be it known that I, JOHN H. ABRAHAM, a citizen of the United States,residing at Lancaster, in the county ot Lancaster and State ofPennsylvania, have invented certain Improvements in Cigar-Bunching.Machines, of which the following is a speciiication.

This invention relates to improvements in machines for bunching androlling the' fillers of cigars in their binders; and the objects of theimprovements are, first, to feed the fillers in given quantities intothe receptacle in which they are wrapped in their binders in such.manner as to avoid the friction and strain produced by machineryT inwhich the surfaces of the parts slide upon veach other; second, toautomatically produce a pocket in the forming-apron for the reception oteach bunch of fillers as it is delivered from the hopper, and, third, toautomatically open and close the wicket of the chtite by which thelilling material is conveyed from the hopper at the proper time todeliver each bunch of iillers into the pocket formed for its reception.I attain these objects by the mechanism illustrated in the accompanyingdrawings, in which- Figure 1 is a side elevation of a machine embodyingmy invention,partiallyin section, showing the pocket formed and thewicket open. Fig. 2 is a similar view showing the treadle depressed andthe operating parts in a different position, showing the cylinder inposition to deliver the bound filler and with the wicket closed; Fig. 3,a front view ot" the machine with part of the frame A, shell of theroller M, and front of the hopper B cut away to afford a view of theoperating parts. Fig. et is a rear elevation of the buncher with part ofthe frame and rotating cylinder cut away to show the spring 15'; Fig. 5,a top or plan view showing the arrangement `and mode of operatimg` thefeed-screw and agitating-arms. Figs. 6 and? show end and front views ofa modification in the rotating cylinder and the spring-roller wherebythe pocket is formed. Figs. 8 and 9 are similar views of anothermodication, the parts being partially cut away in the side view. Figs.10 and ll show an enlarged end and top view, the former partially insection on line x, of the rotating cylinder, forming-apron, and rollers,with the belt drawn down to form a pocket and the binder andtobacco 4 inplace as seen just before the rolling process begins; Figs. l2 55 and13, similar views of the same with the tobacco et in the position itoccupies while the rolling mechanism is in operation; Figs. 14 and l5,views of the same showing the cigar 4 after the rolling has beencompleted. Fig. 6o

1G shows an end view ot rolling device after the rolling is completed.

Similar letters indicate like parts throughfout the several views.

In the drawings, A represents-the supporting-frame; B, the hopper, and Ca feed-screw extending through said hopperl from back to front, andhaving bearings in the rear plate b of the same, and supported by thearms b in front. horizontal plates b2 b3, forming the double bottom ofthe hopper, and carries the filling material received on it from theopening b in the upper plate b2 to the opening d in the front plate,whence it is delivered into the chute D.

Motion is given to the screw by means of a strap or chain E, attached tothe treadle at e. This strap passes up from the treadle over the rollerd, mounted on the rod a', eXtend- 8o narily be used; and the depressionof the 9o treadle through the strap E and the collar F, with the pawl fengaging the ratchet f', imparts such motion. Inside of the collar Fthere is a coiled spring e which acts to throw the collar back and takeup the slack in the 95 strap as soon as the treadle is raised.

IThe size of the opening b4 in the plate b2 is regulated by means of aslide d', resting on the said plate in front of the opening, and isrendered adjustable by means of screw-'roo The screw is located betweenthe 7o The collar has a pawl f atthreaded pins c, projecting throughslots c in the sides of the hopper, and provided with set-n uts c2.

G G are two agitating-shafts extending longitudinally through thehopper, and having radially-projecting agitating arms or spurs g, whichrake the tobacco filler toward and into the opening h and upon thefeedscrew. The shafts G G are rotated by means of the coggearing at therear of the hopper. In this gearing', c3 represents a driving-wheelfastened rigidly to the spindle of the screw, which meshes with thecog-wheel g on the shaft G', that engages in turn the cog-wheel g2 ofthe shaft G. The drivi 11g-wheel sets out from the end of thehopper, andthe cog-wheel g' is of considerably greater thickness than the driver,so that it engages eog-wheel g, located back of the driver, and causesit to move in the opposite direction. The feed-screw projects su fliciently far beyond the front plate of the hopper to carry the tobacco iillerto the outside thereof, where it is received by the chute D. A wicket 7Lis hinged near its upper edge to the chute, and is opened at the propertime to deliver its load by the leverI.

.I represents the rotating cylinder in common use with bunching-machinesof this class, and K the forming-apron, or apron surrounding the same.Zt' is a recess extending across the cylinder to receive the slackportion of the apron drawn down into it to form a pocket when itis underthe chute to receive the charge therefrom, the amount being sufficientforl the filler of one cigar. As the cylinder is rotated forward thefiller is wrapped in its binder and revolved in the apron between thecylinder and two rollers Z Z, placed one above the other immediately infront ot' said cylinder and close enough to it to prevent the cigarbeing rolled from passing around with the apron.

Immediately in front of the recess Zt' there is another similar recess7.3 in the cylinder, in which the ends of the apron are secured. lVhenthe latter recess is brought opposite the rollers Z Z the bound filleris discharged into it, and after being taken therefrom the cylinder ispermitted to be revolved backward until it resumes its origin alposition. The forward movement of the cylinder is produced by a strap t,connecting it with the treadle T and wound about and secured to one endof the cylinder inside of the bearing. rl`he reverse movement isproduced by a spring t', coiled about the opposite end of the cylinder.This spring has only to lift the slack of the strap Z, as the treadleitself is raised by a powerful coiled spring S, connecting said treadlewith the part of the frame above it.

M represents a roller journaled below the rollers Z Z, in which there isa strong coiled spring' m, adapted to hold the said roller in position.To this roller there are attached cords m', which are wound about it.One of these cords is placed on each side of the roller under the edgeof the forming-apron, and

each has one end attached to the edge of the apron. This roller is solocated and the cords are attached to the apron at such points as todraw the slack of the apron down into therecess Zt' and form a pockettherein when the said recess is .under the chute. Then the cylinder isrevolved forward by the depression of the treadle, the apron is carriedwith it, and the cords m', which also pass about the rollers Z Z,follow, revolving the roller M and tightening the spring therein, sothat when the cylinder is rotated backward and the recess k broughtagain beneath the chute the apron, by means of the spring m and thecords m', is automatically retracted into the said recess to form apocket.

To keep the slack of the apron in position under th e chute when thecylinder is retracted, and thus facilitate the formation of the pocket,I have a roller N journaled in the frame above the cylinder and in suchclose proximity to it as to hold the slack of the apron in front of itwhen said cylinder is revolved backward. This roller may be covered, ifdesirable, with a rubber or other jacket to prevent more et' the apronslipping backward between it and the cylinder than is necessary tofollow the movement of the same.

Figs. G and 7 illustrate a modification of the method by which the apronK may be drawn down to form a pocket in the recess Zr.. In applying thismethod the roller h supplied with the retracting-spring, as in theconstruetion first described, is located inside of the cylinder J andjournaled in the ends thereof. The retracting-cords m are wound aboutthe roller and pass out of slots ai, cut in the eylinder entirely aroundit, and located adjoinin g that part which carries the apron K.

The connection between the treadle and the spindle of the screw and ofthe latter with the shafts of the agitatorsv is so arranged that eachdepression of such treadle may cause such revolution of the screw as todischarge sufficientA filling material into the chute to form one cigarand to have said agitators act during such revolution. The slide d regu*lates the amount of tobacco thrown down upon the screw through theopening in the plate b2, so that the said amount may be varied to suitthe size of the cigar te be made.

The connections of the lever for opening the wicket of the chute, thebelt-receiving recess in the cylinder, and the spring-roller and cordsconnecting the same with the belts are so constructed that as saidrecess reaches its position under the chute the pocket is formed, andimmediately thereupon the wicket is opened and the tobacco filler justreceived therein from the feed-screw is discharged into the pocket.

The operation of my invention is as follows: The loose tobacco is placedin the hopper B, and when the treadle T is depressed the screw C iscaused te revolve for the purpose of feed ing the tobacco through theside of the hop- IOO IIO

passes around suitable rollers, and is wrapped at its upper end aroundthe collar F, secured to the end of the shaft of the screw C. At thesame time that the screw is caused' to revolve for the purpose offeeding out the tobacco the two shafts G G', provided with arms or spursg, are caused to revolve for thepurpose of stirring up the tobacco inthe hopper and preventing` it from clogging. The loose tobacco is forcedby the screw C into the chut-e D, which is provided with a wicket h. Atthe same time that the treadle T is depressed the strap r causes thecylinder J and pulley jx to revolve, which pulley is provided with a pinj for the purpose of engaging with the hooked rod h2, which operates thelever I, for the purpose of opening the wicket h at the proper time todeliver the tobacco in the pocket formed by the apron K when thecylinder is in the position shown in Fig. l.

The cylinder J is provided with recesses k 7;', which extend lengthwisewith the cylinder.

In the recess 7c a pocket is formed by the slack of the belt being drawndown therein by means of the spring-actuated roller M, from which thecords extend for the purpose of catching hold of opposite edges of thebelt and drawing the slack down into the recess to form the pocket toreceive the tobacco from the chute D.

In connection with the cylinder J the rollers Z l are used, and aroundwhich the apron Klis made to pass, both ends of the belt being fastenedto the cylinder in the recess k. Also used in connection with thecylinder is the roller N, which operates in connection with the apron Kfor the purpose of preventing the slack of the apron from moving pastthe recess lo. NVhen the treadle is released it is instantly returned toposition by the spring S, connected thereto, and then the spring orsprings connected io the cylinder instantly cause it to revolve into theposition shown in Fig. l, so as to receive the filler in the usualmanner. As soon as the cylinder is forced forward by its spring into theposition shown in Fig. l the cords connected to the springactuatedroller M draw the slack of the apron down into the recess r to form apocket. Then the treadlc is depressed, the cylinder is rotated into theposition shown in Fig. 2, so as to roll the filler.

Having thus described my invention, whatI claim as new, and desire tosecure by Letters Patent, is-

l. In a cigar-bunching machine, the combination, with the rotatingcylinder having a recess formed in its side, a spring-actuated roller,cords extending therefrom, and the apron to which the cords areattached,whereby` the slack of the'apron is drawn down into the recessto form a pocket, substantially as set forth.

2. The combination, in a cigar-launching machine, of the apron, thecylinder or surface upon which the apron is placed, and which isprovided with 'a recess, a springactuated roller, and guiding-rollersfor the belt and cords, which are attached to opposite edges'of theapron, so as to draw its slack down into the recess to form a pocket,substantially as shown.

3. In a cigar-bunching machine, the combination of the hopper and thechute having a wicket with the rotating cylinder having a recess formedin its side, the apron, and a spring-actuated roller, cords extendingfrom the roller and connected to opposite edges of the apron, wherebythe slack of t-he apron is drawn down into the recess to form a pocket,substantially as described.

4. In a cigar-bunching machine, the combii nation, with the surface onwhich the bunch is rolled, said surface having a recess formed therein,of the apron and the cords fastened to said apron, and having a springattachment whereby the apron is drawn down into the recess to form apocket. p

5. In a cigar-bunching machine,the combination, with the surface uponwhich the bnn ch is rolled, and which is provided with a recess whichextends across its surface, of the apron and a spring attachment wherebythe apron is drawn down into the recess to form a pocket, substantiallyas shown.
